我有大约10k的图像,我需要将它们上传到blob存储。有没有批量上传的工具?我也愿意编写自己的应用程序。

看看ClumsyLeaf cloud explorer。让我们像FTP客户端一样将文件上传到blob。 Alterntaively Azure Storage Explorer。同样的想法。

两者都允许您从目录中选择文件并一次上传。从来没有尝试10000,但它应该工作。

Cloud Storage Studio也很不错。

您可以免费获得30次试用,因此没有风险。特别是如果这是一次性交易。

您可以使用windows azure powershell从azure存储上传/下载多个文件。

要上传多个文件,可以使用以下命令行。

ls -File -Recurse | Set-AzureStorageBlobContent -Container upload

要下载多个blob,可以使用以下命令行。

Get-AzureStorageBlob -Container containername -Blob blobname | Get-AzureStorageBlobContent

有关详细信息,请参阅MSDN页面。

我发现由于使用少量线程,现有工具要么是付费软件要么是缓慢的。 TBH甚至我尝试过的付费应用程序都很慢,但Azure API非常简单,所以我最终编写了自己的命令行工具,它叫做azupload:

https://github.com/bviktor/azupload

它是免费的,根据MIT许可证发布。它有C#和Java版本,因此您可以在Windows和Linux上轻松部署它。

C#版本使用内部.NET调度程序来启动新线程(我的comp通常是10-ish),而Java版本启动的线程数与指定的数量相同。这是非常高效的,我用700张图片(总共20MiB)和100个线程测试了它,它在8秒内完成了上传。

当然,你必须找到一个平衡点。如果启动太多线程,最终会因Java VM的开销而减慢速度。此外,如果你上传大文件,上传100个线程没有意义,因为在这种情况下,瓶颈将是带宽,而不是像许多小文件那样的事务开销。此外,如果您上传许多文件,JVM将以比关闭它们更快的速度打开文件,所以一段时间后您将获得Too many open files个例外(对于我来说,13k文件发生在我身上@ 100)线程)。因此,根据经验,文件越小,线程越多,但你应该停在50左右。

非常感谢您的反馈!
